Psychiatrist Livingston's earlier journals of the death from leukemia of his six-year-old son, Lucas, were first published in the San Francisco Chronicle's Image magazine, where they evoked wide and warm response. In those writings, he detailed the grueling regimen (including a bone-marrow transplant from the author) that Lucas endured, bequeathing to the family a lesson about the power of the human spirit. The current journal details the depth of Livingston's struggle with the loss of Lucas and the earlier suicide of an older son, and with his rage at the medical technology that failed his child. A poignant account of an anguishing life-changing experience. (Apr.)
